wmertens - there's a great video intro to this on the Tech page. Swipe the tiles at the bottom to see the different demos.
Next character, next word, end of line - are all supported. In both cursor navigation, and text selection contexts.
Home, End, PageUp and PageDown are all supported on the green layer of these same locations as those cursor arrows.
The mappings all align with the logical associations. (PageUp is green layer up arrow).
It has a full inverted T right on the home row.
Cut, Paste, Copy, Undo, and redo are all there too.
The idea is to have everything you need for editing right at your fingertips on home row, so you don't have touch the screen to manipulate text briskly and precisely.
And of course, all of this can be modded for personal needs with MultiMap (cursor mods will be in a later release of MultiMap).
